Abstract
During cruise SO 136 of the German Research Vessel ‘SONNE’ to the Tasman Sea and Southern Ocean (16. Oct. – 12. Nov. 1998 from Wellington/NZ to Hobart/Tasmania) numerous deep-sea sediment samples were collected with such devices as a box-corer, an epi-benthic sledge and a multi-corer. These samples yielded extremely rich fossil and living ostracod faunas from water depths ranging between 562 m and 4520 m. Herein, the authors present taxonomic revisions and functional morphological interpretations of one of the more common elements of the ostracod assemblages: the platycopids. In total, from the open-ocean waters west and south of New Zealand, 7 platycopid species were recovered alive, all of which are new to science and are described in this text. Five species belong to the genusCytherella, however, for 2 unusual platycopid species we have erected 2 new genera:Cytherella hiatus n. sp.,Cytherella intonsa n. sp.,Cytherella corpusculum n. sp.,Cytherella plusminusve n. sp.,Cytherella permutata n. sp.,Grammcythella dyspnoea n. gen. n. sp. andInversacytherella tanantia n. gen. n. sp.
Kurzfassung
Während der Forschungsfahrt SO 136 mit dem deutschen Forschungsschiff ‘SONNE’ in die Tasmann See und den Südozean (16. Oktober bis 12. November 1998 von Wellington/Neuseeland nach Hobart/Tasmanien), wurden zahlreiche Tiefsee-Sedimentproben mit Geräten wie Kastengreifer, Epibenthos-Schlitten und Multicorer gewonnen. Diese Proben erbrachten überaus umfangreiche fossile und lebende Ostracodenfaunen aus Wassertiefen zwischen 562 m und 4520 m. Mit vorliegender Arbeit unterbreiten die Autoren eine taxonomische Revision sowie eine Interpretation der Funktionsmorphologie einer der häufigeren Elemente der Ostracoden-Vergesellschaftungen: die Platycopiden. Insgesamt wurden im offenen Ozean westlich und südlich Neuseelands sieben platycopide Arten lebend gefangen, die alle als neue Taxa beschrieben werden. Fünf dieser Arten gehören der GattungCytherella an, während für zwei ungewöhnliche platycopide Arten zwei neue Gattungen aufgestellt werden:Cytherella hiatus n. sp.,Cytherella intonsa n. sp.,Cytherella corpusculum n. sp.,Cytherella plusminusve n. sp.,Cytherella permutata n. sp.,Grammcythella dyspnoea n. gen. n. sp. undInversacytherella tanantia n. gen. n. sp.
